Benefits of technology

This approach ensures that air resources are fully utilized by synchronizing the transmission of data packets across multiple services within the same transmission period, enhancing the efficiency of data synchronization and reducing resource wastage.

Problems solved by technology

The delay relates to the largest transmission delay and a processing time.

first embodiment

A First Embodiment

[0050]An operating and maintaining system configures parameters for a BM-SC, which include the length of a synchronization period, a serial number of the synchronization period and the start time of the synchronization period. Similarly, an eNB also configures the length of a transmission period, a serial number of the transmission period and the start time of the transmission period. Because of the largest transmission delay and the largest processing delay from the BM-SC to the eNB, the start time of the synchronization period on the BM-SC and the start time of the transmission period on the eNB which have the same serial number are different, and the start time of the transmission period on the eNB is lagged for a period of time. For example, if the start time of a synchronization period with a serial number of 0 is 10:00:00:000 on the BM-SC, the start time of a transmission period with a serial number of 0 is 10:00:00:650 on the eNB, and is lagged for 650 ms.

A Second Embodiment

[0057]An operating and maintaining system configures parameters for a BM-SC, which include the length of a synchronization period and a transmission delay. In this embodiment, the length of the synchronization period is 640 ms, and the transmission delay is 10 ms.

[0058]The BM-SC adds the same time stamp to all data packets of the same service received in one synchronization period; or the BM-SC adds the same time stamp to all data packets received in one synchronization period, no matter whether the data packets belong to the same service. The time stamp is different from the serial number of the synchronization period, but is absolution time.

[0059]If the BM-SC adds the same time stamp to all received data packets of the same service in one synchronization period, the time stamp added by the BM-SC to data packets of a certain service received in one synchronization period is represented by the following formula:

time stamp=absolution time at which the MB-SC receive...

third embodiment

A Third Embodiment

[0065]An operating and maintaining system configures parameters for a BM-SC, which include the length of a synchronization period and a transmission delay. In this embodiment, the length of the synchronization period is 640 ms, and the transmission delay is 10 ms.

[0066]In this embodiment, the BM-SC adds a time stamp to the first data packet of each service, does not add the time stamp to other data packets of the service, but needs to add an Elapsed Octet Counter and a Packet Number to other data packets of the service. Here, the first data packet is the first data packet during the service, if the first data packets of two services are received in the same synchronization period, the BM-SC adds the same time stamp to the first data packets of the two services. In this embodiment, the time stamp of the first data packet exclusively indicates a synchronization period in which the first data packet is received, e.g. a serial number of the synchronization period or ab...

Abstract

The present invention discloses a data synchronization method and system. The method includes that: a first device adds a time stamp to a received data packet and transmits the data packet to a second device; the second device determines a transmission period to which the data packet belongs according to the time stamp of the data packet, and transmits data packets of different services which belong to the same transmission period by using air resources corresponding to the transmission period after the data packets of the different services which belong to the same transmission period are multiplexed. By the technical scheme of the present invention, air resources can be fully utilized.

Description

TECHNICAL FIELD[0001]The present invention relates to data communication technologies, and more particularly to a data synchronization method and system.BACKGROUND ART[0002]With the development of communication technologies, a mobile communication system has been evolved into a System Architecture Evolution (SAE) system. The SAE system includes an Evolved Universal Terrestrial Radio Access Network (E-UTRAN), and the E-UTRAN includes a core network and a wireless access network.[0003]FIG. 1 is schematic diagram illustrating an E-UTRAN in a SAE system in the prior art. As shown in FIG. 1, an evolved Node B (eNB) belongs to the wireless access network, and the core network includes a Mobility Management Entity (MME) and a Subscriber Gateway (S-GW). The eNB is adapted to provide a wireless interface for User Equipment (UE) such as a handset and so on. The MME is adapted to manage mobility contexts and session contexts of the UE, and protect user information related to security. The S-GW...
